Geology

Geology is the study of the earth, the materials of which it is made, the structure of those materials, and the processes acting upon them. It includes the study of organisms that have inhabited our planet.

An important part of geology is the study of how Earth's materials, structures, processes, and organisms have changed over time. Geology gives insight into the history of the Earth, as it provides the primary evidence for plate tectonics, the evolutionary history of life, and past climates.

In modern times, geology is commercially important for mineral and hydrocarbon exploration and exploitation, and for evaluation of water resources, mining, and metallurgy; Ore Genesis.
